Smudging, or other rites involving the burning of sacred herbs or resins, is a ceremony practiced by some Indigenous peoples of the Americas. While it bears some resemblance to other ceremonies and rituals involving smoke from other world cultures, notably those for spiritual cleansing or blessing, the purposes and particulars of the ceremonies, and the substances used, can vary widely between tribes, bands and nations, and even more so between different world cultures. In traditional communities, Elders maintain the protocols around these ceremonies and provide culturally specific guidance. The smudging ceremony, by various names, has been appropriated by others outside of the Indigenous communities as part of New Age or commercial practices.
